Patented Dec. 10, 1929 JOSEPH B. KAUSAL, OF CHICAGO, ILLINOIS v r V CROSS-AISLE LIGHT Application filed June 18,

H10 area of the cross aisles so as not to c'ast light upwardly into the auditorium where dark ness or semidarkness is desired during the performance, and which will ofier the least possible obstruction in the limit-ed space Other objects will appear hereinafter.-

' The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming. a part of this specification, and in which:

Fig. 1 is a perspective view of a device of .member 20 having rectangular light openings 21 and 22, covered by a light directinghood member 23. Referring to Fig. 3, it will be the invention mounted in position between the backs of two adjoining theater seats;

Fig. 2 is a front elevational view of the device with the hood portion in section;

Fig. 3 is a vertical sectional view taken on the line 33 of Fig. 2; Fig. 4 is a horizontal sectional view taken on the line H of Fig. 2; and

Fig. 5 is a side elevational' view showing the manner of mounting the removable hood member.

The device of the invention is intended to be secured between two adjoining theater seats below the normal line of vision of persons in the audience, and is further intended to cast a soft glow of light in each lateral direction whereby sufficient illumination is provided throughout the lower area of the cross aisles by placing a device at every alternate space between adjoining seats. The construction and arrangement of the device is such that the light is cast'laterally and rearwardly at the proper angle to enable patrons to read programs and furnish illumination on the floor of the cross aisles for the convenience of .50 patrons in taking or leaving their seats. At

light openings'21 and 22, and as member 23 is 1928. Serial N0. 286,161.

the same time, the'source of light being concealed, and the amount and extent of the illu mination being limited, the lights need not be extinguished during the performance.

As illustrated in. therdrawings, the preferred embodiment of the device comprises a cylindrical supporting member 10 into which is fitted a bracket member 11 having a horizontally extending plate 12 supporting a two piece socket 13which carries lamp 14; 1 The socket is preferably smaller than the-standard size and a small 10 watt lamp hasbeen found to furnish a suflicient amount of illumination for the purpose. In modern seating construction, a T-iron is usually employed as part ofthe supporting structure between two adjoining seats and furnishes a convenient and rigid mounting forthe lightv ing device. The two downwardly extending stems15 and 16 of the members 10 and 11, re-" spectively, may be boltedto the vertical extending T-iron 17 extending betweenthe two seats 18 and 19. V

The lamp casing consists of a cylindrical j noted that hoodimember 23 contacts with the vertical portion 24 of member 20 between the conical in shape at each side of the central member 20, the light is divided and cast downwardly and slightly outwardly at each .side of the device. Member 23 may for convenience beremovably attached to the sup- -porting member 10 by means of bayonet screws25 adapted to fit into slots 26. g A safe v and convenient meansof leading wires to the device is by the use of metallic conduit 27, oval in shape and adapted to extend'through opening 28 in member 11 and conduit 27 may be secured to T-iron 17 byineans of clamps 28. As will be seen in Fig. 4,'the device is shaped so as to fit into the depression occurring at the meetingedgesof two adjoining theaterseats and thus the objection hereto fore encountered in. lights of this type be-. cause of the projection into the space of the cross aisle and the consequent obstruction and inconvenience'to patrons has been overcome.

The light is compact so as to occupy a minimum of space and is so constructed to fit between two ad oining seats so as not to project into the cross aisle to any greater extent than the central curved portion of the seats. Furthermore the construction and arrangement or the light openings and shading portions are such that the lights may remain lit preferred form of construction for carrying my invention into eifect, this is capable of i variation and modification without departing from thespiritof the invention. I, therefore, donot wish 'to be limited to thepreeise details ot'construction set 'forth, but desire toavail myself of such variations and modifioa'tions as come'within the scope of the appendedclaimsi Y I ":Having described my invention, what I Y claim as new and desire 'to secure Letters .iPat ent is: I
